Machine Learning and CDS Transparency

By William A. Hyman – One of the many questions in the design and use of Clinical Decision Support software is whether or not the user can recreate the logic used by the system in reaching its conclusions and recommendations–or alerts, or suggestions.


A Surfeit of Software Snafus

By William Hyman – We are of course increasingly dependent on software in our professional and personal lives. We are also increasingly familiar with software problems ranging from malfunctions to cybersecurity holes.


Cyclical Conundrum in Complication Prediction

By William A. Hyman – A popular form of Clinical Decision Support is the prediction of forthcoming complications. I have commented on reports of such systems before, and another example has been posted recently, in this case seeking to predict cardiovascular complications from CT scans.



ONC Explains Who Isn’t Covered by HIPAA

By William A. Hyman – Discussions of HIPAA and HIPAA violations are common in these pages, and are of course important for those subject to the requirements and wrath of HIPAA. I have also heard that “What about HIPAA?” is a question that can kill an app developer’s bid for funding.



Predicting Death Using EHR Data

By William Hyman – Computer Decision Support usually takes the form of software generated patient specific recommendations based on patient attributes in the EMR. A recent study takes a somewhat different approach by using EMR data to identify hospital patients who are at risk of death, but offers no treatment suggestions, it just says the patient has an elevated risk of dying.


CDS Moves Compliance from Dismal to Dismal

By William Hyman – One use of a Clinical Decision Support system (CDS) is to remind doctors of what the “established” standardized methodology is. One key issue here is established by whom? Another is, depending on complexity, why the clinical staff doesn’t follow the established procedure whether or not it is supported by a CDS.
